python - 为什么我的 Python 代码可以在 Jupyter Notebook 中运行，但不能作为脚本运行？

Question

我正在尝试使用 Wand 打开 PDF 作为图像。如果我在 Jupyter Notebook 中运行下面的代码，它工作正常。如果我从命令提示符将代码作为脚本运行，我会收到一条错误消息。出于某种原因，该模块在 Jupyter Notebook 之外运行时不会加载。有没有人有什么建议？

Python 3.7.2(64 位)

from wand.image import Image

with Image(filename="C:/test.pdf", resolution=300) as img:
    print(type(img))

这是错误信息:

Traceback (most recent call last):

    from wand.image import Image

两周前修复的魔杖和收藏品似乎存在问题:https://github.com/emcconville/wand/pull/398

尝试更新您的魔杖安装:pip install --upgrade wand
